Found a reference to an article and the journal name is abbreviated?
E.g. [2012] 2 C.M.L.R. 40 or JutD 2011, p. 21-24 (afl. 5).
Need to find the article but no clue what the full journal name is?
1) Use the Cardiff Index to Legal Abbreviations! This database allows you to search for the meaning of abbreviations for English language legal publications, from the British Isles, the Commonwealth and the United States and even covers a wide selection of major foreign language law publications.
2) For Dutch abbreviations (e.g. found in Data Juridica) use the Kluwer afkortingenlijst/citeerwijzer. Use the key combination CTRL-F to quickly search through the PDF-list.
3) Still struggeling with an abbreviation? The KU Leuven afkortingenlijst juridische tijdschriften also covers Belgian, (Dutch), German, French and Swiss journals. Use the 'flags' to switch country or use the little search box (zoeken, select 'alle landen') on the right hand site.
Furthermore, know that both Westlaw and HeinOnline offer a 'citation search'. In Westlaw this function is called Find by citation and can be found at the World Journals tab. In HeinOnline the function can be found in the Law Journal Library and is called Citation Navigator. Note, the results may vary.
